示例1: copyLater
void SlotVisitor::copyLater(JSCell* owner, CopyToken token, void* ptr, size_t bytes)
{
ASSERT(bytes);
CopiedBlock* block = CopiedSpace::blockFor(ptr);
if (block->isOversize()) {
ASSERT(bytes <= block->size());
// FIXME: We should be able to shrink the allocation if bytes went below the block size.
// For now, we just make sure that our accounting of how much memory we are actually using
// is correct.
// https://bugs.webkit.org/show_bug.cgi?id=144749
bytes = block->size();
m_heap.m_storageSpace.pin(block);
}
ASSERT(heap()->m_storageSpace.contains(block));
LockHolder locker(&block->workListLock());
// We always report live bytes, except if during an eden collection we see an old object pointing to an
// old backing store and the old object is being marked because of the remembered set. Note that if we
// ask the object itself, it will always tell us that it's an old black object - because even during an
// eden collection we have already indicated that the object is old. That's why we use the
// SlotVisitor's cache of the object's old state.
if (heap()->operationInProgress() == FullCollection
|| !block->isOld()
|| m_currentObjectCellStateBeforeVisiting != CellState::OldGrey) {
m_bytesCopied += bytes;
block->reportLiveBytes(locker, owner, token, bytes);
}
